Users interact through terminals<\/p>             <p>Step 3: File sharing architecture:  With the invent of PCs File sharing architecture evolved. PCs download files from shared locations,                  perform jobs and submit to the shared locations. Over time the PC LAN became over crowded for this paradigm.<\/p>                <p>Step 4: Client-server architecture evolved. File servers were replaced by database servers who respond to users requests and supply only the included data rather than total file. Network load decreased<\/p>                    Two Forms of Client-server architecture:                        <ol>                            <li> Two Tier                           <\/li><li> Three Tier                        <\/li><\/ol>              <p><b>Two Tier:<\/b> Client layer(Sytem Interface) and a Server layer (DBMS).

Frameworks can also utilize other commonly available middleware services for that application domain. For a specific domain,                   a framework usually provides better solutions than general middlewares as they are especially designed for that domain. It is usuaaly easier for the developers to use frameworks for application development and testing. Frameworks can also be called middlewares themselves because they provide the same\/similar purpose. Many middlewares do not have any visible part but frameworks usually have visible parts.<\/p> From: http:\/\/sitestree.com\/?p=5308<br \/> Categories:111<br \/>Tags:<br \/> Post Data:2010-03-03 03:53:50<br \/>\n\n    Shop Online: <a href='https:\/\/www.ShopForSoul.com\/' target='new' rel=\"noopener\">https:\/\/www.ShopForSoul.com\/<\/a>\n    (Big Data, Cloud, Security, Machine Learning): Courses: <a href='http:\/\/Training.SitesTree.com' target='new' rel=\"noopener\"> http:\/\/Training.SitesTree.com<\/a> \n    In Bengali: <a href='http:\/\/Bangla.SaLearningSchool.com' target='new' rel=\"noopener\">http:\/\/Bangla.SaLearningSchool.com<\/a>\n    <a href='http:\/\/SitesTree.com' target='new' rel=\"noopener\">http:\/\/SitesTree.com<\/a>\n    8112223 Canada Inc.\/JustEtc: <a href='http:\/\/JustEtc.net' target='new' rel=\"noopener\">http:\/\/JustEtc.net (Software\/Web\/Mobile\/Big-Data\/Machine Learning) <\/a>\n    Shop Online: <a href='https:\/\/www.ShopForSoul.com'> https:\/\/www.ShopForSoul.com\/<\/a>\n    Medium: <a href='https:\/\/medium.com\/@SayedAhmedCanada' target='new' rel=\"noopener\"> https:\/\/medium.com\/@SayedAhmedCanada <\/a>\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
